Welcome to Jungle Breaks 
the site that tells you where many of the classic D'n'B/Jungle
breakbeats were sampled from.
Searching for these breaks on the web, I came to the conclusion
that you've got to give the original funky drummers their
dues  If you want to use their beats, why not sample them from the songs
that they originally appeared on?  This site tells you about
those original songs...
On the breaks pages you'll find samples of the breaks to
download. For the listens choose "Open this file from its current location". The listens are in
11,025 Hz, 8-bit, mono WAV format. For the downloads
choose "Save this file to disk" or right-click the link
and choose "Save Target As...". The downloads are mostly in
44,100 Hz, 16-bit, mono WAV format.
